JULIUS STOCKHAUSEN, OF CREFELD, GERMANY. I

Serial No. 532,682.

Be it known that I, JULIUS SrooKHAUsEN,

a subject of the German Emperor, and residing at the city of Crefeld, Germany, have invented a new and useful Detergent and Production of Same; and I do hereby declare the following to be a full, clear, and exact description of the same.

The present improvements relate to a compound or emulsion, especially useful as a detergent soap for dry cleaning, chemical washing and as an emulsifier in the removal of fat and grease.

Soap (such as ordinary laundry .soap, Marseilles soap, or olive oil soap) is only in a small measure (about 5%) clearly soluble in the products obtained by mixing a sulfooleaginous body with a hydrocarbon-chlorid (such as carbon-tetrachlorid, etc.). My new compound, which is characterized by the inclusion of alcohol, will, however, form a clear solution with a considerably greater quantity of soapup to thirty or forty per,

cent. of soap. At the same time, freezing of the solution or emulsion, during coldweather, is stayed. This effect isfurther increased when soap-of'castor oil, preferably neutral soap of castor oil is also added to the compound.

My new compound consists of a mixture containing alcohol, neutral soap of castor oil, soap (such as ordinary laundry soap,

' Marseilles soap, or olive oil soap),a sulfooleaginous body (such as sulfonated fats, or

oils, or fatty acids or. oleic acids, or Turkeyred oil, or sulfonated soaps obtained by treating the before mentioned sulfona'ted products with excess of caustic soda, and mentioned sulfonated products with excess of caustic soda, and hydrocarbonchlorids (such as tetrachlorid of carbon, tetraor pentachlorethane, trior perchlorethylene, etc.)

To produce my new compound, I may proceed as follows:

Example I: 100 parts of soap obtained by treating sulfonated oils and fats with 7 to 9% of caustic soda preferably at higher temperatures, which soap is commercially known as monopol-soap are dissolved inlittle water. The solution obtained is mixed with 60 to 80 parts of tetrachlorid of carbon, 2 to 10 per cent. alcohol, and with 10 to 30 parts of ordinary laundry soap, instead of which olive oil soap may be employed. v

Example II: 100 parts of Turkey-red oil are mixed with 30 to parts of tetrachlorethane and 2 to 10 per cent. alcohol, finally the mass thus obtained is dissolved in little water. The solution obtained is mixed with 10 to 30 parts of laundry soap or olive oil soap.

To either of the products obtained as aforesaid, I may add 5 to 15 parts of neutral castor oil soap.

The mixture can be employed with excellent results for removal of fats, or for 'washing, imparting to some goods-a peculiar luster.

1. A new compound containing alcohol, soap of castor oil, a sulfo-oleaginous body and a hydrocarbonchlorid.
